So I know what I want as my main for launch from last beta so I figured this time around I'd try my alt interest which is pyromancer. After looking around I notice a lot of people are taking warlock as 3rd soul for mana tapping. I'm curious to know if people are just doing 5 points into lock and putting the last another 5 into Improved Exposure in the Elementalist tree or if I should put an extra 5 into Opportunity in the Warlock tree. For leveling which is going to be a more solid addition to my efficiency? Thanks for any advice.

The other option I was thinking was skip Warlock and do 5 points into Archon fire buff talent and the other 5 into Improved Exposure.
